difference between DJI Phantom 2 receivers

[nitro thrasher]

Can someone tell me the difference between DJI receiver v4 and DJI receiver Part 31? On rc711.com the Part 31 is only $9 while the other one is $39. I have a spare transmitter and just need another receiver so I can use them on my f330 project. I will post the links to both parts on the website. Thanks

No clue, I've never heard of two versions of that Rx and the descriptions effectively say the exact same thing. There's 2 versions of the 5.8GHz Rx but it's news to me if the same is true of the 2.4GHz D-bus/FASST unit.

Have you tried contacting the vendor and asking them?

Maybe one is used or removed from a/c as and upgrade and the other is 'new'.
